Abstract

Microemulsion abrasive-free jet polishing (MAFJP) technology is a novel non-abrasive removal technique that exhibits unique advantages in polishing nonlinear KDP optical material. During MAFJP, the nanoscale water cores in MAFJP fluid impact and slip on the KDP surface, thus leading to contact with the KDP atoms and achieving defect-free removal of KDP through water dissolution. Dissolution is the inverse process of crystal growth and exhibits significant anisotropy. This work first investigated the orientation-determined KDP dissolution removal characteristics. At first, we gained insights into the impacting process of nanoscale water cores based on molecular dynamics simulation and then established an MAFJP removal function model to describe the removal process for KDP. The model considers the dynamic impacting and slipping dissolutions of (001), (010), (100), (111), I-type, and II-type crystal planes, and the final calculated results match perfectly with actual experimental results. This research elucidates the mechanism of orientation-determined MAFJP on KDP, and will promote the application of MAFJP technology in the polishing of single-crystal anisotropic optical materials.

微乳液无磨料喷射抛光中 KDP 晶体从纳米到宏观尺度的取向决定去除特性的研究与建模

微乳液无研磨剂喷射抛光（MAFJP）技术是一种新型的无研磨剂去除技术，在抛光非线性 KDP 光学材料方面具有独特的优势。在 MAFJP 过程中，MAFJP 液体中的纳米级水芯会在 KDP 表面产生冲击和滑动，从而导致与 KDP 原子接触，并通过水溶解实现无缺陷 KDP 的去除。溶解是晶体生长的逆过程，具有显著的各向异性。这项工作首先研究了取向决定的 KDP 溶解去除特性。首先，我们基于分子动力学模拟深入了解了纳米级水核的撞击过程，然后建立了一个 MAFJP 去除函数模型来描述 KDP 的去除过程。该模型考虑了 (001)、(010)、(100)、(111)、I 型和 II 型晶面的动态冲击和滑动溶解，最终的计算结果与实际实验结果完全吻合。该研究阐明了取向决定的 MAFJP 对 KDP 的作用机理，将推动 MAFJP 技术在单晶各向异性光学材料抛光中的应用。
